Principles of Operation

Air from the cellar is drawn over an evaporative drip pad that is saturated with water from a distribution tray. As the air passes through the pad, it absorbs moisture through evaporation of the water. This raises the humidity of the leaving air that returns to the cellar. The humidistat, located in the cellar, will automatically turn on the humidifier whenever the cellar humidity is below the set point and turns it off when the cellar humidity reaches set point. The recommended set point is 50% to 70% RH for wine cellars. The humidity level is high enough to prevent corks from drying out and low enough to prevent mold from forming.

Maintenance of the Humidifier


A regular maintenance program prolongs the life of the humidifier and help maintain proper humidity levels in the cellar. Frequency of cleaning and replacement of the drip pad depends on the inlet water conditions and the cleanliness of the cellar air. The drain system may also trap dust and dirt. When water no longer stays on the pad or mineral build-up has started to reduce airflow, the pad needs to be replaced. For these reasons we suggest you check the drain on a monthly basis and confirm there is a steady flow of water while unit is in operation. Clean drain if needed. Also monthly, check for unusual noise or vibration, which could be a sign that the debris may be trapped and needs to be removed. Refer to your humidifier’s installation operation and maintenance manual for step-by-step instructions on how to clean the humidifier and replace the evaporative drip pad.
